2 Claims.

The present invention relates to improvements in threshing machines.

The primary object of my invention is the provision of a device thatthreshes the grain from the straw and'separates the straw from the grainin one cylinder.

Another object of my invention is the provision of means in the cylinderfor governing the speed of the straw through the cylinder.

Astill further object of the present invention is the provision of meansin the cylinder allowing the separated grain to leave the cylinder.

A still further object of th epresent invention is the provision of athresher in which the num ber of parts have been reduced to a minimum.

A still further object of the present invention is the provision of athresher in which all of the moving parts are carried by a single shaft.

Other objects and advantages thereof will be clearly understood from astudy of the following detailed description when read in conjunctionwith the attached drawings, wherein:

Figure 1 is a front elevational view of my improved thresher.

Figure 2 is a rear elevational view of Figure 1.

Figure 3 is an end elevational view taken on line 3--3 of Figure 1, andlooking in the direction of the arrows, parts being shown fragmentarily.

Figure 4 is a view similar to Figure 1, portions being shownfragmentarily and in section.

Figure 5 is a bottom plan view of my device and illustrating my novelbar grate.

, Figure 6 is a section view taken on line 6-6 of Figure 4.

Referring now to the drawings, the numeral 9 represents the thresher,and it comprises a frame It, having a plurality of vertical, horizontaland transverse members, and a horizontal cylindrical housing I I, havingan inlet opening [2 and a stalk The cylindrical housing H is interposedbetween the frame members I4 and I5, and it comprises a lower portion l6and an upper portion ll. The lower portion I6 is supported by straps l8and I9 that are rigidly secured to the lower portion by any suitablemeans, such asby rivets 20. Theends 2| and 22 of strap member l8, and 23and 24 of strap member 19 are rigidly secured to the frame mem .bers l4and I5 by any suitable means, such as by rivets 25. The lower portion I6is provided with a grain discharge opening that comprises a plurality ofrods 26 that are in spaced relation. Secured in any suitable manner toone end of the lower portion I6 is a volute housing 21 having anaperture 28 and an enlarged opening 29 for a purpose to be laterdescribed, the stalk discharge opening l3 being provided in the housing21. To the opposite end of the lower housing I6 is secured in anysuitable manner a disk 30 that forms an end- Wall for the housing H andit is provided with a central aperture 3 I.

The inlet opening I2 is provided in the lid 32, and on the innerperipheral wall 33 of the lid 32 aresecuredin any suitable manner aplurality of helical lunate members 34 that are in spaced relation. Thelid 32 has hinge butts 35 that are secured to the lid by rivets 36. Thebutts 35 engage companion butts 3'! that are secured by rivets 38 to theframe member IS. A rod member 39 connects the butts 35 and 31, providinga means for swinging movement of the lid 32. On transverse members 40and 4| are bearing brackets 42 that are secured to the transversemembers by bolts 43, the lid having a handle '58. Within the housing llis'a longitudinal coaxial shaft 44, the ends of which pass throughapertures 28 and 3| the end portions 45 and 46 being seated in thebearing brackets 42. Mounted on the shaft 44 and secured thereto in theusual manner is a pulley wheel 41, and within the volute housing 21 andmounted on the shaft 44 and secured thereto in the usual manner is a fan48. Also mounted on the shaft 44 adjacent the opening I 2 is a thresher49 that comprises finger disks 50 and 5| that are rigidly secured to theshaft in any suitable manner, stri metal members 52, the strip membersbeing in spaced spiral relation, each strip being provided with studs53, the ends of the strip members being connected to the disks 50 and 5|in any suitable manner. The shaft 44 also has mounted thereon aplurality of finger disks 54, one edge of each of the fingers beingdisposed at an angle, the fingers of each disk being in staggeredrelation to the adjacent disk. To one edge of the finger disks ,54 issecured one face of metal strips 56 as illustrated in Figure 6, thestrips being positioned as illustrated in Figure 4 of the drawings,forming a reel *51, the strips being secured to the fingers in anysuitable manner.

In the operation of my thresher, the pulley wheel 41 is connected with asource of suitable power (not shown), the pulley wheel rotating theshaft 44 and the members carried by the shaft. The material to bethreshed is feed intothe opening l2 where it is engaged by the thresher49, the studs 53 threshing the grain from the straw. As the grain isthreshed from the straw the grain sifts through the grain dischargeopening 26, the straw or chafi is carried towards the volute housing 21.by the movement of the reel 51 which separates the grain from the straw,the straw impinging against the lunate members 34, and due to theangular position of the lunate members, the straw gradually feedstowards the volute housing 21, through the enlarged opening 28 where itis picked up by the fan 48 and discharged through the opening l3.

From the above description it can be seen that I have combined manyoperations in the threshing of grain into" one structure, thuseliminating many moving parts, reducing the cost of the machine andthreshing grain in a shorter time than is now required.

Having described my invention in detail,'it will be obvious to thoseskilled in the art, that various changes and modifications may be madetherein without departing from the spirit or scope of the appendedclaims.

What I claim .is:

1. A thresher comprising a horizontal hollowcylinder having a lowerportion, an upper portion and a' housing adjacent one end thereof, the

lower portion having supporting straps and agagement with bearings, aplurality of finger discs mounted on said shaft, the fingers of some ofsaid discs connected by diagonally disposed members forming a beater,said members having studs, the fingers of the other of said discsconnected to metal strips forming a helical reel, the heater and reelbeing connected together and positioned in said cylinder, a fan on saidshaft and disposed in said housing, the said lower and upper portionsbeing hingedly connected.

2. A thresher comprising a frame having hearing brackets, a horizontalhollow cylinder having a lower portion, an upper portion and a housingin said frame, the lower portion having supporting'strapsand a pluralityof rods in spaced relation forming a grain discharge opening, said upperportion having an intake opening and lunate bars on the inside thereof,said housing having a receiving opening in one side wall and a dischargeopening, the ends of said straps being secured to said frame supportingsaid cylinder and housing in said frame, the said lower and upperportions being hingedly connected, a shaft axially disposed in saidcylinder and-housing, the ends of said shaft engaging said bearingbrackets, a spiral beater, a helical reel and a fan carried by saidshaft, said spiral beater and helical reel disposed in said cylinder,the said fan housing in said housing.
